摘要
针对异步电动机起动母线压降计算中存在的问题,结合柴湾站计算实例,分析了高压线路阻抗、变压器阻抗、低压线路阻抗、其它负荷阻抗和起动电机阻抗对母线压降的影响。阐述了正确的计算方法和应注意的问题。
In the design process of electric part of discharging waterlog pumping station of middle and smallscale, which form can be taken to start asynchronous motor is determined through the calculation of bus voltagedrop of low pressure when actuating motor. Aimed at the existed problem in this calculation and with the casecalculation of Chaiwan station, the influence of impedance such as high pressure transformer, low-pressure,other loads and actuation of motor to bus voltage drop is analyzed. The correct calculation method and whatshould pay attention to are stated.
